The half-quantum group U^>=0
Z. Wang, H. X. Chen
Let U^>=0 denote the half quantum group for a fixed simple Lie algebra. We examine some properties and representation of U^>=0. We prove that the Hopf algebra U^>=0 is not quasi-co…

Representation theory of a Class of Hopf algebras
Z. Wang, H. X. Chen
The representations of the pointed Hopf algebras and $\su$ are described, where and $\su$ can be regarded as deformations of the usual quantized enveloping algebras $U_q(\m…

Geodesics on weighted projective spaces
Victor Guillemin, Alejandro Uribe, Zuoqin Wang
We study the inverse spectral problem for weighted projective spaces using wave-trace methods. We show that in many cases one can "hear" the weights of a weighted projective space.
